Crossrail has shortlisted five companies for the £400m contract to design and provide track installation and equipment for London's new Crossrail network tunnels.

The shortlisted firms are: Alstom Transport / TSO / Costain joint venture; BAM Nuttal / Ferrovial Agroman / Kier Construction joint venture; Balfour Beatty Rail; Laing O'Rourke Construction / Volker Rail joint venture; and Rhomberg Bahntechnik / Alpine Bau / FCC Construction joint venture.

Crossrail programme director Andy Mitchell said, "Contract will be awarded in early 2013, providing the chosen contractor with sufficient time to undertake detailed design and planning before fit-out work commences in 2014."

Tunnel construction is expected to start next month with the first tunnel boring machine commencing work at Royal Oak station.

Construction work on the 21km of twin-bore tunnel, stretching across the capital via central London and the Docklands, is expected to be completed in 2014. A fit-out of the tunnels with necessary track and overhead power equipment will then be installed to allow Crossrail trains to operate from 2018.

This phase of the construction includes installation of about 40km of track, overhead electric conductor rails to power trains, ventilation and drainage systems.

The new Crossrail tunnels will need about 50 ventilation fans, 40km of walkways, 60 drainage pumps, 30km of fire mains and lighting across the entire length.

After the contractor is finalised, the selected contractor will start fit-out simultaneously from both Royal Oak and Plumstead portals.

The fit-out works will be carried out within the entire tunnelled section of the Crossrail route between Royal Oak, Pudding Mill Lane and Plumstead Portals, and it is expected that the selected contractor will start fit-out simultaneously from both Royal Oak and Plumstead portals.

The C610 Systemwide main works contract includes the C630 tunnel mechanical and electrical systems contract, while tender will be finalised in April 2012.
